如何在 node.js 中使用 window.sessionstorage

Question

I store a hash in session storage using javascript like:

window.sessionStorage.setItem('test', true);

How do I read this key using node.js?

Answer 1

You don't.

sessionStorage is a browser side API for storing values locally for the life of the browser session, that does not automatically get transmitted to the server. NodeJS is a framework and engine for creating server side applications.

Perhaps you're needing the functionality of cookies .

Answer 2

I have made a simple package to emulate browser's sessionStorage .

https://www.npmjs.com/package/node-sessionstorage

You can use it like this:

const storage = require('node-sessionstorage')

storage.setItem('foo', 'bar')

console.log('item set:', storage.getItem('foo'))

Answer 3

I created this npm package since i'm having the same issue on my own projects,

    npm i sessionstorage-for-nodejs

again this is my npm package and i created it.

    const sessionStorage = require('sessionstorage-for-node');

    sessionStorage.setItem('id', 'value');
 
    console.log('product: ', sessionStorage.getItem('id'));
 
    sessionStorage.removeItem('id', 'value');

Answer 4

You can use express-session module on Node.js:

$ npm install express-session

But it can be more complicated than the way you use window.sessionStorage , eg some security needs to be taken care of. For express-session documentation, click here . For more info about how it works, click here .
